' l'. MOLD FOR MAKING ROOFING TI'KLES.

Application filed August 22, 1927,. Serial No. 214,771, and in GreatBritain August 2.8, `1928.

This invention relates to rooting tiles and has for its object toprovide an improved mold for Jforming valley tiles for use with thecommon forms of interlocking tiles and is particularly applicable to theforming of concrete valley tiles.

l/Vith the forms of moldpand pallets previously employed for forminginterlocking concrete tiles it has not been possible to orm `means forforming the valley tiles hereinafter described rand claimed.

In the accompanying drawings which illustrate the invention, i. v l

Fig. l represents an interlocking concrete valley tile to produce whichis the object of the invention, n

Fig. 2 represents th-e frame for the pallet or mold on which the tile isproduced;

Fig. 3 represents the frame with the pallet in position;

Fig. i represents the rear portion of the frame with the verticalmembers tilted over to give access to the underside of the pallet Aforremoval of the latter with the molded tile upon it;

Fig. 5 represents the front portion of the frame with the hingedrib-forming mold in position.

The valley tile which has on each side two ribs a is shown in Fig. l andit is to be understood that the central vertical line in this figurerepresents the bottom of the valley; at one side a channeled projectionZ) is provided while at the other side a ridge c with an underneathchannel Z is provided.

The ordinary rectangular intermeshing tile with which the valley tilesmatch are provided at one edge with a rib c which iits over thechanneled projection Z2, a similar channeled projection being providedon the other edge. v

The mold :trame comprises a quadrilateral base e provided at the frontwith a hinged block m for forming the front portion of the tile and withside members or rails j, Ic between which the pallet '20 is placed andwhich l projects above the latter to an extent corresponding to thethickness of concrete required and thus act as striking-off gauges.

At the back of the base c vertical members f, g are hinged; thesemembers interlock with each other by a groove D and are held in verticalposition by a rear hinged strut 71,.'

The pallet or mold p is of ridgedrform and` is provided with recesses B,C correspondingkv to the ribs to be formed on the valleytile.v The peakof the pallet is supported upon an angular seat A carried on the membere, and the edges are supported on ledges, one, E, ot which is shown inFigs. 2 to 4.5

A hinged nib-forming mold Z is provided with a recessin corresponding tothe nib to be formed on the underside of the front of the valley tile.It is to be understood that the pallet is of ridged formand that'thevalley tile is molded upside down so that the nib has to project upwardsfrom the tile as molded.

The mold Z is hinged at the side of the frame and normally occupies theraised position shown on Figs. 2 and 3 ofthe drawings.

Fig. 3 shows the parts inposition for the concrete to be molded.

Concrete is then placed on to the pallet and is caused toiill therecesses therein by means of a trowel or other suitable means; by meansof an ordinary striker working along the edges 7, y' and g, 7o thethickness of the concrete is determined. It now remains to form the nibi and the interlock channel Z on the back of the tile. f

To form the nib, the hinged member Z is, swung over to the positionshown in Fig. 5 and concrete is tamped into the recess fn.; the member Zis then hinged back. To form the interlock channel Z a striking rod x ofrectangular section of which the end portions only are shown on Figs. land 2 is driven into the concrete in the edge of the tile, this rodresting in a. notch 1 in the member f and against a ledge s on the fronthinged blowck m; the rod is then slid out of the groove so formed. i

The tile is now molded and now has to be lremoved on its pallet from theframe to a place where it hardens or cures.

For this'purpose thefront block m is tilted forward on its hinge F, andthe rear strut 71 is folded back thus enabling the vertical F ig. 4 andpermitting the operator to put his hand under the pallet and liftl itout.

Although the form of the invention illus--y trated'is specially intendedfor use in forming concrete tiles it may also be employed With ysuitableminor modifications to the forming of interlocking tiles of clay orother plastic material.

I claim K l. A mold for forming interlocking valley tiles comprising ahinged frame and a ridged n pallet.

mold for forming interlocking valley tiles comprising a quadrilateralbase member, rear hinged vertical members, a. front hinged block, and a.hinged nib-forming member.

3. A mold for forming interlocking valley tiles comprising a basemember, rear hinged vertical members, an angular seat for the peak of apallet carried by one of said Vertical members, ledges for the sides ofthe pallet carried by the'base member, a front hinged block, andI hingednib-forming member.

In testimony Whereoz I aiix my signature.
